dc.description.abstract

Electroactive polymers are polymers that switch reversibly between insulating and conducting states. Their unique properties enable them to be used in a wide range of applications including electrochemical capacitors, sensors and electrochromics. This research is focused on conjugated, high-nitrogen content, heterocyclic monomers for stable n-doping polymers. To minimize band gap, compounds of significantly different electronic properties are coupled. Pyrimidines, pyrazines and benzenes will be used as precursors to couple with thien-2-yl, 3,4-ethylenedioxythien-2-yl and 1,3,4-thiadiazolyl rings. The mixing of electron-rich rings with high electron affinity heterocycles facilitates efficient electron mobility and stabilizes n-doping of resultant polymers.
